COMBINED OUTS IDE ANDINSIDE CALIBER-S. 7

Application filed March 26, 1919.

To all whom it may concern Be it known that I, NILs SvENssoN, a citizen of Sweden, residing at Malmo, Sweden, have invented certain new and useful Improvement-s in Combined Outside and Inside Calipers, of which the following is a specification.

The present invention relates to improve ments in combined outside and inside calipers, the object of the invention being to provide an improved device of this character in which the legs or shanks of the calipers are pivotally connected with a handle consisting of two parts pivotally connected with each other in such a way that the calipers may be folded together to a suitable pocket size, without offering any projecting sharp corners or points that tear the pocket. The shanks of the calipers have such a length in relation to the parts of the handle that they are completely covered by said parts after having been folded together.

Combined calipers of this type are already known, such calipers being provided with a handle consisting of two pivotally connected parts, but in these calipers one shank of the outside calipers and one shank of the inside calipers are made in one piece and thus it is impossible to fold the instrument in such a way that the extreme ends of the shanks are covered when in a clasped state.

The invention is illustrated in the accompanying drawing. Figure 1 is a front view of the calipers in an opened position. Fig.

2 is another front View of the same when partly opened. Figs. 3 and 4 are two side views of the same calipers when clasped.

The handle consists in a known way of two parts 2 and 8 pivotally connected with each other by means of a pivot 1. WVhen the shanks of the calipers are opened to the position shown in Fig. 2, one shank of one of the parts can coact with one shank of the other part in the same way as in hitherto known instruments of this class, and as one of the shanks of the inside calipers very well may be used for outside measuring (Fig. 2) and also a shank of the outside calipers may be used for inside measuring it is evident that the instrument used in this Specification of ietters Patent.

way covers dimensions about twice as large as a simple pair of calipers.

According to the invention two shanks 4: belonging to the outside calipers are pivotally connected with one of theportions 2 of the handle by means of a pivot 5 and two shanks 6 belonging to the inside calipers are 1n the same way pivotally connected with the other portion 3 of the handle by means of the pivot 7. All the shanks are placed on the sides of the parts of the handle facing each other in such a way that said parts after the clasping of the instrument cover the shanks (Fig. 4). Between the parts of the handle a distance piece 8 is provided at the pivot 1, said distance piece having such a thickness that there will be room for all the shanks between the parts of the handle. The parts of the handle are of equal length and the shanks of the calipers are a trifle shorter thanthe free distance between the pivots 5, 7 and the distance piece 8 so that the shanks may be turned wholly around.

The instrument described has a length when'clasped corresponding to only one of the parts of the handle and notwithstanding it can be used for measuring within the same limits as an instrument of the double length.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. Combined outside and inside calipers comprising a handle consisting of two parts pivotally connected with each other, two shanks forming outside calipers pivotally connected for independent rotation with one of the parts of the handle by means of a common pivot, and two shanks of the inside calipers in the same way connected with the other part of the handle.
